Tyrannosaurus rex’s image has seen major adjustments over the past century.

Five Discoveries That Changed Our Understanding of T. Rex Forever, From Warm Blood to Lips

Paleontologists are still unraveling the secrets of the world’s most famous dinosaur, such as its outward appearance or the way that it hunted. With each new finding, our view of the “tyrant lizard king” has gotten a little clearer—and sometimes has radically shifted

Wiring diagram of an adult male fruit fly's central nervous system

This New Brain Map Shows Every Nerve Cell in an Adult Male Fruit Fly’s Central Nervous System. Here’s Why That Matters

The recently released “connectome” joins a previously completed map of an adult female fruit fly’s brain. The digital 3D diagrams allow scientists to trace precise neural paths in the bugs’ brains, which can unlock secrets about the organ in humans

Elongated scales form leg-like structures at the tip of the spider-tailed horned viper's tail, creating a decoy arachnid that the predator can use to attract birds.

The Tip of This Snake’s Tail Looks Like a Spider. But Inside, Its Bones Are ‘Bizarrely Normal’

High-tech scans reveal the first detailed look at the internal anatomy of the spider-tailed horned viper. The findings shed light on little-known snake vertebrae and highlight the difficulty of predicting what an animal looks like from its skeleton

Amud 7 was discovered in a cave in Israel in 1992.

Neanderthal Kids Grew Up So Fast—at Least Compared With Their Human Peers—Thanks to Genetic Adaptations to Their Environment

Scientists think Neanderthal children may have had faster growth rates because larger bodies tend to retain heat more effectively than smaller ones

The clitoris is larger than most people think, and much of the organ is internal.

Scientists Just Made the Most Complete Map of the Clitoris’s Sensory Nerve Network. Here’s What They Found

Cultural taboos around female sexuality have hindered research on the organ. But a new study provides pivotal insights that can inform important surgeries and health care

Common eastern bumblebee queens use underwater breathing and anaerobic metabolism to survive when submerged.

Bumblebee Queens Breathe Underwater to Survive Drowning, Revealing How They Can Live Submerged for a Week

After scientists accidentally discovered that the common eastern bumblebee can withstand flood conditions, they wanted to investigate what makes that super-ability possible

Researchers studied the combination of muscles and breaths that the tiny birds use as they strike trees with their beaks

Ned (right) likely won't be able to reproduce unless another left-coiling snail is found.

A Rare, Left-Coiling Snail Needs Help Finding a Mate. New Zealanders Are Looking for Its 1-in-40,000 Match

Known as Ned, the creature needs a fellow left-coiling garden snail to reproduce—but the species almost always has shells that coil on their right side

A common octopus (Octopus americanus) raises its arm in southern Florida.

Scientists Map the Ways Octopuses Use Their Complex Arms, Revealing Preferences for Certain Tasks

The cephalopods appear to favor using their front arms, according to a new study, though their back arms help with locomotion

The wide, basin-shaped pelvis of modern humans helps us walk upright on two legs and give birth safely to babies with large heads.

Scientists Discover Key Evolutionary Changes to the Pelvis That Helped Humans Walk Upright

A new study delves into the development of the ilium, the largest bone in the pelvis, and the genes that underpin its formation

Cataracts, pinkeye and other ocular disorders are linked to heat, air pollution and higher UV exposure

Psychiatric neurosurgery, originally known as psychosurgery, involves operating on the brain to alter its function.

What Does the Future Hold for Psychiatric Brain Surgery?

For some patients, removing brain tissue can help treat OCD and other disorders. But ethical concerns remain
